Hello all,
As much as I hate to admit it I came from an anti-gun family in california. Being 22 I am now learning how to shoot properly. Getting a .22 helped me out but I am now building my first AR. Now I want to build it with flip up Irons, but I am unsure of which to get. I understand loosely that the G.I. Carryhandle/rear reduces the "parallax error"(still learning, feel free to educate me) so I am worried that getting something like Troy Battle sights or Magpul rear sights will not have the same training benefits of just trying to focus on the front post as opposed to constantly lining up the sights and paying less attention to the target. Would getting a Magpul/Troy/other sight that is not specifically designed to reduce parallax error be alright for learning to shoot on? Should I buy a carryhandle/rear sight instead? Any help/information is appreciated, -John |

I'm in the military so I have zeroed and use M16's quite a few times. With that said I'm not infantry, and my job has me using a M240 on a daily basis when deployed. I do own an AR15 and a M16A4 style carrying handle with rear sight and I have a fixed forward sight post. I also use two Aimpoints and an ACOG. Right now I got Troy Industries back up iron sights on my rifle.
With that said I don't understand how there would be any difference of parallax error between flip up back up iron sights (BUIS) and a carrying handle rear sight. As long as you apply the fundamentals and use a consistent cheek weld, sight picture, and sight alignment it shouldn't be any different. Honestly I think you're digging a little too deep into parallax right now, I haven't used high magnification scopes but I'm pretty sure that plays a lot more into that arena that iron sights. I use Troy back up iron sights on my AR15. It gets out the way of my ACOG and Aimpoint well enough. I don't use the weird ass Troy BUIS that is a diamond shape, I think that sh*t is retarded. I use the standard peep sight style Troy BUIS. It works well and is adjustable for windage, and it has a small and large diameter peep sight combo on it. I personally will not be caught alive with a plastic BUIS like MagPul. Now I'm sure its a great sight and all but it is plastic and I refuse to have a sight that is primarily made of plastic. I'm too harsh on my rifle and it would not last. I'm sure others feel different but I don't care how they feel, its my rifle. There are really nice BUIS that come with the same adjustments and peep as a M16A2 carrying handle rear sight, and I want to get one in the future. Since you've been using a .22 LR rifle for a while you'll have to learn the zeroing procedures and the different zeroing ranges and their effects on your point of aim/ point of impact. There are some great threads on here that will show you the different zeroing distances and how they translate to your target depending on its distance. Just make sure you zero your rifle depending on the BARREL LENGTH. Different barrel lengths and even ammo weights (55gr to a 77gr for example) will effect your zeros point of impact. Shooting iron sights, I love shooting the carrying handle sights. Its old school and just feels right to me. BUT if you plan on using any kind of optic on your rifle, which I have 3 myself, you'll want to throw on a flip up BUIS. This will allow you to move your BUIS out of the way to make room for your optics. Now there are brackets you can attach to the top of your carrying handle to mount an optic, I have one of those brackets myself, but it is not the preferred method. Your sight is raised above your barrel even higher so zeroing is harder, and its best to mount an optic to the upper receiver itself so you have a solid mounting connection. With that said, a carrying handle can take more of a physical beating than a BUIS. BUIS are very tough, but if you were to take a hammer to each, the carrying handle would win. So each has its benefits and drawbacks. I'm not saying you need to learn how to shoot, but since this is your first AR15 I would recommend searching on the forums for how to shoot a M16 / AR15. There are some old school Marine Corps shooting videos you can find on youtube that are superb. I learned quite a few things from them that I was never taught in basic training. Learn the fundamentals and shooting will become easy. |

Second the vids on the youtube. Check em out. 60crewdawg laid it out pretty well. I would just add, you don't need to buy some fancy flip ups to be good. In terms of what they do, they aren't better per se.
If you just want some irons and dont care about fashion or spending a lot of dough: If you don't want an optic, id get a detachable carry handle in the EE. If you do, the matech, the real mil issue flip, is about the best bang for the buck as its $30-$50 on the EE and ebay. Just watch out for fakes if youre on ebay... there are airsoft clones. But that goes for almost any ar part... |
| For fixed sights the LMT rear sight is basically the carry handle rear sight without a carry handle. I'd Highly recommend as mil spec as possible for irons......and learn how to adjust them accordingly. This will build a solid shooting foundation for when you move up to optics. |
| The M16/M4/AR15 family of rifles have some of the best (if not the best) iron sight setups in the world. I would get a mil-spec height carry handle, and learn to use it. You may find out that is all you need. While I do admit that red dot sights have their uses, I am more comfortable with irons, and that is what I use. |
